Authorities are looking into the possibility of unmarked graves at a cemetery in Southern California.
The Press-Enterprise reports a spokesman for the Riverside County District Attorney's Office has confirmed an investigation is underway at the cemetery in Corona. No charges have been filed and no arrests have been made in the case.
Police were seen excavating dirt at Corona Sunnyslope Cemetery last week.
According to a search warrant, authorities intended to use ground-penetrating radar "to detect anomalies consistent with pre-existing burials" and to excavate in search of remains in areas without clearly marked graves.
